Dental crowns — reliable restoration of a badly damaged tooth
A crown fully encases the tooth and protects it from further breakdown. Modern materials — metal-ceramic, CAD/CAM and zirconia — provide a natural appearance and long service life. First consultation is free.
Book a consultationA dental crown is a fixed prosthetic restoration that completely covers the visible portion of a tooth. It is prescribed when a tooth has been destroyed by more than 50% and a filling can no longer adequately restore its shape and function. A crown restores masticatory load-bearing capacity, protects root canals after endodontic treatment and returns the tooth to a natural aesthetic appearance.
At iDent we offer several crown options depending on the clinical situation and patient preferences. For the anterior zone, CAD/CAM or all-ceramic restorations are appropriate — they are indistinguishable from natural teeth. For posterior teeth under heavy load, metal-ceramic or zirconia crowns are used. Digital diagnostics are performed before treatment; in complex cases a CT scan on the PaX-i3D Smart is taken.
Indications for a dental crown
- Tooth destroyed by more than 50% — a filling cannot withstand the load
- After root canal treatment — the tooth becomes brittle and requires protection
- A cracked or fractured tooth at risk of further splitting
- Significant shape or colour defects not correctable by restoration
- Abutment tooth for a fixed dental bridge
- Implant crown — the final element of the prosthetic restoration
Crown fabrication and placement step by step
1
Consultation and preparation
The clinician examines the tooth and, where indicated, orders X-rays or a CT scan. If endodontic treatment is needed it is completed first. For severely broken-down teeth a composite build-up core is fabricated to provide a reliable foundation for the crown.
2
Tooth preparation and impression
The clinician prepares the tooth under anaesthesia, reducing it circumferentially by the crown wall thickness. A precise C-silicone impression or digital scan is taken and sent to the laboratory.
3
Temporary crown and laboratory fabrication
While the laboratory produces the permanent crown (usually 5–10 working days), a temporary acrylic or CAD/CAM crown is placed. It protects the prepared tooth and allows you to preview the final shape.
4
Try-in and cementation
At the next visit the clinician checks the fit, occlusion and appearance. Once the patient approves, the crown is cemented with a permanent adhesive. The result is immediately functional and aesthetic.
Why choose crowns at iDent
- Precise tooth preparation: composite build-up core for heavily damaged teeth as a reliable base
- CAD/CAM technology — crown milled from a solid ceramic block, no hand-layering
- Wide material choice to match budget and clinical requirements
- Digital impression of both arches in one appointment — more accurate than conventional silicone
- Written warranty on the prosthetic restoration
- Open daily 9:00–20:00, no days off. Address: 14 Pryvokzalna St., Kyiv
Crown longevity depends on the material, the quality of tooth preparation and home oral hygiene. Metal-ceramic crowns last an average of 10–15 years; zirconia crowns 15–20 years or more. A properly made and well-maintained crown is indistinguishable from a natural tooth both visually and functionally.
After the permanent crown is cemented, routine maintenance is all that is required — twice-daily brushing, an oral irrigator and a professional check-up every 6 months. For implant-supported crowns, technical servicing of the full restoration is planned jointly at your review visits.
Frequently asked questions
Tooth preparation is performed under local anaesthesia — the patient feels nothing. Mild discomfort for 1–2 days afterwards is possible and easily managed. Cementation of the permanent crown is entirely painless.
Typically 5 to 10 working days from the impression. Throughout this time the patient wears a temporary crown that protects the tooth and looks presentable. A CAD/CAM crown can be produced by the laboratory in 2–3 days.
A crown has walls 0.5–1.5 mm thick, so the tooth must be reduced by exactly that amount around its circumference — ensuring the crown does not increase the tooth's size or disturb the bite. Preparation is as conservative as possible and carried out under the protection of anaesthesia.
